Undefined partial names cause TypeError to be thrown

[rpkilby]

We have a bug in our code that results in an undefined partial name for a split second. This causes a TypeError to be thrown before assertAsset can display a meaningful warning. fiddle

The problem is that resolveAsset assumes that the asset id will be a string, even though this is not necessarily the case when the id is dynamically bound. A few possible solutions:

• Force the asset id to a string before camelization
• Only perform camelCase and PascalCase lookups if isString(id)
• Assert that the asset id is a string, although all calling code would now have to handle that case. Partial/component/other asset registration would probably need to do the same as the following is technically legal: Vue.partial({}, '<div>lolol</div>'
